Specification of Letters Patent.

Patented NOV. 26, 1918.

Application led March 19, 1918. 4Serial No. 223,326.

T0 all whom t may concern Be it known that I, JOHN D. KENNEDY, a citizenof the United States` residing at New Kensington, in the county ofWestmoreland and State of Pennsylvania, have invented new and usefulImprovements in Collapsible Barrels, of which the following is aspecification.

This invention relates to a collapsible barrel and has for its primaryobject to provide an article of this character capable of withstandingexcessive strains and further capable of being quickly disconnected andarranged in a folded position.

An object of the invention is to provide a cap of such a construction asto reinforce the body of the barrel against inward as well as outwarddistortion and to allow the cap to be readily connected to the body.

Besides the above my invention is distinguished in the novel form oflocking means for connecting the cap to the body in a secure manner butallowing the same to be readily disconnected when force is applied in apredetermined direction.

With these and other objects in view the invention will be betterunderstood from the following detailed description taken in confnectionwith the accompanying drawing wherein:

Figure l is a vertical sectional view of the barrel.

Fig. 2 is a detailed horizontal sectional view through the cap.

Fig. 3 is a detailed horizontal sectional view on the line 3 3 of Fig.1.

Fig. 4 is a sectional view of an improved form of cap.

Fig. 5 is a sectional view of another form of cap.

Fig. 6 is a plan view of the securing element.

At the start I wish to call attention to the fact that although I haveshown the body of the barrel provided with arcuate corrugations I wishit to be understood that the same may be square or of any other suitableshape in cross-section.

My invention consists of a body 1 composed in this particular instanceof two sections 2 and 3. Each section at a central point is providedwith a groove 4 providing a bead 5 that materially reinforces thecentral portion of the barrel. Seated in the groove 4 is a tie wire 6for forcing the sections into engagement with each other and holding thesame against displacement. The connection between the ends of the tiewire 6 may be accomplished in any suitable manner. As clearly shown inFig. 3 it will be seen that the section 2 has its vertical edge portion7 forced into the lianged edge S of the section 3.

As the caps 9 and 10 are identical in construction the followingdescription will bev limited to cap 9. This cap 9 has its centralportion 10a depressed so as to be arranged within the body of the barreland to cooperate with the depending flange 11 to fornr a groove 12 thewalls of which engage with, and inclose the corrugated end of the barrelbody as clearly shown in Fig. 2. From this construction it will be seenthat thesections 2 and 3 are materially reinforced against inward oroutward movement due to the engagement between the corrugations and thewalls of the groove 12 as clearly shown in Fig. 2. Thus it will be secnthat this construction in combination with the bead 5 enables thesections 1 and 2 to withstand excessive inward or outward strain.

In the preferred form of my invention the locking device for the capconsists of a metallic strip 13 resting upon the central portion 10 andhaving its ends 14 passing through alining openings 15 in the cap andthe body of the barrel. This strip is of resilient character so that thecentral p0rtion may be bowed when the ends are being inserted in theopenings. When removing the strip it is necessary to arrange aninstrument under the central portion of the strip 13 and bow the sameupwardly so as to retract the ends from the openings. A very importantfeature of my invention is that the {iange 11 completely closes theprotruding ends of the strip 13 so that the same will be protected frombeing mutilated or displaced.

That form of my invention illustrated in Fig. 4 is identical with` thatI have just described with the exception that the cap 16 is centrallyprovided with a transverse rib 17 which besides reinforcing the centralportion of the cap, constantly bows the strip 18 so as to insure a tightconnection between the ends of the strip and the walls of the openingsin the cap and body. In Fig. 5 I have shown the cap 19 and lockingelement 20 so arranged and constructed that the top portion of the sidewalls of the cap is not formed with an opening. In this particularinstance an opening 21 is arranged in the flange 22 and the strip 23 isof sufficient length to allow the ends to project beyond the flange andflattened as indicated at 24. The protruding ends of the element 23 maybe twisted by the use of an ordinary pair of pincers. v

From the foregoing description taken in connection with the accompanyingdrawing it will be apparent that I provide a barrel of substantialconstruction and which may be very readily folded for shipping purposes,and besides, the operation of the locking element 13 and the positionthereof is such that the strain of the contents of the barrel againstthe cap willl act in a direction at right angles to the movementnecessary to removing the ends of the locking element 13 from engagementwith the body.

Having described my invention, what I claim is:

A shipping barrel comprisinga substantially cylindrical body providedwith longi- Copies of this patent may be obtained for vecentseach,byaddressing the tudinally extending corrugations, said body beingprovided at each end with a pair of diametrically opposite slots, a headdisposed upon each end of said body and formed as a circular memberhaving its central portion depressed to .form an inner fiange bearingagainst the inner periphery of said cylindrical body, an annular flangeformed at the outer edge of the head in spaced substantially parallelrelation to said first named flange and engaged upon the outer peripheryof said body, said inner flange being provided with a pair ofdiametrically opposite slots adapted to be brought into registrationwith the associated pair of said first named slots and a resilient stripdisposable within the depressed portion of the' head upon the outer facethereof with the ends of said strip engaging through saidregistering'slots, the ends of said strips being insertible within saidslots when said strip is in bowed` position.

In testimony whereof I aiiiX my signature.
